SPECIFICATION forming part of Letters Patent No. 597,583, dated January18, 1898.

Application filed April 22, 1897. Serial No. 68 3,346. (No model.)

To all whom it may concern:

Be it known that I, EMIL M. KOPKA, of Adrian, in the county of Lenaweeand State of Michigan, have invented new and useful Improvements inFences, of which the following is a full, clear, and exact description.

The invention relates to wire fences; and its object is to provide newand useful improvements in fences whereby the horizontal or strand wiresare securely fastened to the posts or pickets and ample provision ismade to allow proper expansion and contraction of the strand-Wireswithout damage to the posts.

The invention consists of certain parts and details and combinations ofthesame, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indicate corresponding parts inall the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a sectionalplan view of the same on the line 2 2 of Fig. 1, and Fig. 3 is atransverse section on the line 3 3 of Fig. 1.

The wire fence is provided with the usual pickets or posts A, formed bydoubling up a piece of wire to form two vertical members, as illustratedin the drawings. The horizontal or strand wires B are adapted to befastened to the posts or pickets A by locks O,each of which ispreferably made of a single piece of steel or spring wire bent to formtwo loops G 0 having the member 0 common to both loops and the othermembers (3 0 formed at theirinner or adjacent ends withtransverselyextending hooks 0 C respectively adapted to hook upon themember 0 The 'lock 0 thus formed is placed against one side of the postor picket A, so that the ends of the loops project a suitable distancebeyond the two vertical members of the post, and the corre spondingstrand-wire is passed through one end loop, say 0, and then bent overthe rear side of the first member of the post A, and then bent aroundthe front of the shanks of the hooks C 0 and then bent around over therear side of the second member of the post A and passed through theother loop C and then along the line. Thus the strand-wire is formedwith three bends or undulations B, B and B of which the bends B and 13engage the members of the post and the middle bi end 13 passes over theshanks of the hooks C O.

Now it will be seen that by the arrangement described the strand-wirecan readily expand and contract without affecting the position of thepost A, and at the same time the strandwire is securely fastened inplace on the post by the lock C.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination with the picket, and thestrand-wire formed with three bends and engaging the picket on one side;of the lock engaging the other side of the picket and formed with endloops and transverse hooks engaging the member common to both loops,said loops and hooks engaging the bent portion of said strand-wire onthe side opposite the side engaging said picket, as and for the purposeset forth.

2. A wire fence comprising pickets, strandwires formed with three bendsat each post, and a lock made of a single piece of sprin wire bent toform end loops, and transverse hooks, the strand-wire extending throughthe said loops around the post and around the said hooks, substantiallyas shown and described.
